摘要：In previous studies, by regulating the Pb/BHA ratio and pH, lead complexes of benzohydroxamic acid (Pb-BHA) have been proven to be selective for the separation of scheelite from calcium minerals. In this study, sodium silicate (Na2SiO3) and Al-Na2SiO3 polymer were used as depressants for the further separation of scheelite from calcite. Flotation results indicated that both scheelite and calcite were depressed by Na2SiO3, while Al-Na2SiO3 polymer gave good selectivity. The depressing ability of Na2SiO3 for calcite was significantly improved due to the formation of some Al-Na2SiO3 species with
